is it leaking under the fuel drain valve?

I did not remove the filter housing completely when replacing the hoses,where is the fuel drain valve located? The leak only seems to happen when the engine is running.

thats beecause its under pressure when running.
the fuel drain valve is on the back (valve that drains fuel)
im not sure about yours but mine has a tube that runs down and dumps the fuel on the front axle.
theres orings in it that can go bad a cause a leak.
may or may not be your problem. theres several areas in which it can leak.

Check you fuel pump, to see if the leak is coming from under it. There is a vent hole in the bottom that can leak if the pump is going out. You may need an inspection mirror to see it. It will only leak when the engine is running.
